PROBLEM TO BE SOLVED: To provide an organic electroluminescent element material which emits light with high luminescence, and an organic electroluminescent element. SOLUTION: In an organic electroluminescent element holding a light-emitting layer composed of a monolayered or multi-layered organic compound thin film between a positive electrode and a negative electrode which faces each other, at least one layer of the organic compound thin film comprises at least one salt of an anion of a compound represented by the formula [wherein X is -O-, -S- or -N(R8); and R1,R2, R3, R4, R5, R6, R7, and R8 are each a hydrogen atom or a substituent and adjacent substituents may be bonded to form a fused ring] and a metallic cation.
